For years, wind turbine manufacturers have been searching for ways to make direct drive turbines competitive with gearbox turbines. Direct drive technology has been praised for its design, which ...

For example, the radial-flux, direct-drive, rare-earth permanent-magnet (RE-PM) electric generator of the 12-MW Haliade-X wind turbine from GE is approximately 11 meters (or 36 ft) in diameter and ...

Siemens delivers a direct-drive wind turbine for onshore and offshore applications that it hopes will improve cost and reliability of turbines.

The electrically excited synchronous generator (EESG) and permanent magnet synchronous generator (PMSG) are the two types of direct drive generators currently in the market.

The world’s largest direct drive permanent magnet generator for a wind turbine will go up next year off European shores.

Direct-drive generators currently cost more than geared systems and are 15 to 20 percent heavier. Still, GE’s decision to buy ScanWind is smart, says Butterfield.

Part one outlines electrical drive technology, beginning with an overview of electrical generators for direct drive systems. Principles of electrical design for permanent magnet generators are ...

The global direct drive wind turbine market is expected to grow at a CAGR of close to 12% during the forecast period, according to Technavio's latest ...

Advanced Magnet Lab, located in Palm Bay, Florida, is leading one of these projects to develop the first fully superconducting direct-drive generator for large wind turbines with the goal of ...

The product named EcoSwing generator is designed for a +3 MW class direct drive turbine, and will provide enough electricity to power 1000 households.

Technavio's analysts forecast the global direct drive wind turbine market to grow at a CAGR of 11.52% during the period 2017-2021.
